Abstract
Abstract This invention relates to means for protecting the passengers of motor vehicles in case of strong decelerations, notably during a crash. This device comprises, notably in the sun visors, body elements such as door-jambs, edges of window and door frames, etc..., as well as in any other aggressive elements of the passenger compartment of the vehicle, multiple energy-damping inflatable means consisting of bellows inflatable and enclosing a miniaturized generator of gas under pressure, one portion of said bellows being rigidly fastened to the corresponding aggressive element, the other portion being adapted to be easily and readily released during the inflation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
115 words
Device for protecting the passengers of a motor vehicle, comprising: a sun visor; a multiple energy-damping inflatable means disposed in the sun visor and consisting of a support unit comprising a bellows structure adapted to be either spread or expanded, and provided with a gas generator consisting of a stick of explosive powder, one portion of said bellows being rigidly secured to the sun visor from which the passengers are to be protected, and the other portion being releasably secured to said support for releasing said other portion during the inflation of said bellows, said gas generator being adapted to be released electrically by means of an inertia electric switch or any other similar device.
